Hi,

  Based on Olivier Parisy's initial bug report and subsequent
confirmation of the utility of a suggested patch:

  http://gcc.gnu.org/ml/java/2006-08/msg00068.html

I've committed the attached patch to the trunk to make
fallback_backtrace() recognise another sequence of bytes
as an encoding for "pushl %ebp; movl %esp, %ebp".

Tested via an i686-pc-linux-gnu to i686-pc-mingw32
cross-compiler.

Thanks,
Ranjit.
